“The abode and resting-place of the Holy Spirit is humility, love, gentleness and the other holy commandments of Christ. If, therefore, a person desires to grow and to attain perfection by acquiring all these virtues, he must initially force himself to acquire and must establish himself in the first — that is to say, in prayer—wrestling and striving with his heart to make it receptive and obedient to God.”

-St. Makarios of Egypt
